SPECIFICATION forming part of Letters Patent No. 347,506, dated August 1'7, 1886.

Application filed June 2Q, 1886. Serial No. 205.854.

To all whom, it may concern:

Be it known that I, GEORGE PETER, of the city of New York, county and State of New York, have invented a new and Improved Scraper e Sharpener, of which the following specification is a full, clear, and exact description.

This invention relates to a Sharpener for Scrapers; and it consistsin the various features of improvements hereinafter more fully described.

In the accompanying drawings, Figure I represents a side View, and Fig. II a plan or top view, of myimproved machine. Fig. III is a cross-section on line x as, Fig. 1I.

a is the bed-plate provided with feetp at the ends, through which the same is attached to the bench or table..

b is a support embracing the side edges of the bed-plate a, and capable of sliding freely back and forth on the same. The upper part of this support is made in two parts, bb, fastened together by bolts c c, and provided with steel plates d d, inserted on their inner edges and roughened at their inner sides to hold the scraper S, which is clamped between these two parts firmly in its place.

Upon the top of the bed-plate a a perfectlystraight metal plate, w, is fastened parallel with the edges of the bed plate upon which the support slides. V

In the middle of the bed-plate a a frame, f, is arranged, the two legs of which pass through Y the bed-plate a and plate w, and are provided with movable guiding-pieces h, resting upon the top of the plate w, and secured bymeans of set-screws i. These guiding -pieces 7L are regulated to correspond with the width ofthe scraper S to guide the same sidewise and act at the same time to keep the frame f in its place. lThe central part of this frame f sup- (No model.)

ports a block, 7c, carrying on its upper end the cutter-wheel m. This block 7c,with its wheel, passes through the center of the bed plate a and metal plate w, so as to bring the edge of the wheel m in line with the upper surface of the metal plate w.

Below the shank k ofthe block k a set-screw, n, is placed, for raising or lowering the block, andconsequently the wheel m, as may be desired. Near this wheel m guides ov, arranged diagonally, are attached to the metal plate w, to gui@ t-he scraper S in its proper direction.

The operation is as follows: The scraper S, the edge of which has been previously strengthened, is clamped, with its straight edge resting upon the metal plate w, between the two upper plates b l/ of the support b, and securely fastened bythe bolts c c. The support, together with this scraper, is then passed several times backward and forward over the cutter-wheel m,where its receives the desired cutting-edge. The -fixed guides o o bring the lower part of the scraper directly over the wheel m, while the guiding-pieces It hold the same steady sidewise.

1. In combination with the bed-plate a and supportb, the frame f, with guiding-pieces hy h, and cutting-wheel m, substantially as andV for the purpose set forth.

2. In combination with the bed-plate a, pro vided with a metal plate, w, and frame j', the cutting-wheel m, supported in a block, 7.1, and

the set-screw meeting against the shank lc ofv the block k, substantially as and for the purpose described.
